Displaying the nice Values
Oracle Tips by Burleson Consulting

 

Displaying the nice Values

In UNIX, you can use the ps –elf command to see each task and its dispatching priority. In the example below, the NI column shows the existing dispatching priority for the task. Note that there are special nice values—SY (system) and RT (real time)—and these have the highest dispatching priority.

root> ps -elf|more

F S UID PID PPID C PRI NI … SZ … STIME TTY TIME CMD
19 T root 0 0 0 0 SY … 0 … Dec 21 ? 0:00 sched
8 S root 1 0 0 41 20 … 98 … Dec 21 ? 0:00 init -
19 S root 2 0 0 0 SY … 0 … Dec 21 ? 0:00 pageout
19 S root 3 0 1 0 SY … 0 … Dec 21 ? 22:13 fsflush
8 S root 182 1 0 41 20 … 217 … Dec 21 ? 0:00 usr/lib

The above is an excerpt from the "Oracle9i UNIX Administration Handbook" by Oracle press, authored by Donald K. Burleson.
